Description

I included a SolrJ 3.3 dependency into a new project and I noticed needless dependencies transitive show up.

Here is a subset of the output from mvn dependency:tree:

[INFO] +- org.apache.solr:solr-solrj:jar:3.3.0:compile
[INFO] |  +- org.apache.lucene:lucene-core:jar:3.3.0:compile
[INFO] |  +- commons-httpclient:commons-httpclient:jar:3.1:compile
[INFO] |  |  \- commons-codec:commons-codec:jar:1.2:compile
[INFO] |  +- org.apache.geronimo.specs:geronimo-stax-api_1.0_spec:jar:1.0.1:compile
[INFO] |  +- org.apache.zookeeper:zookeeper:jar:3.3.1:compile
[INFO] |  |  +- log4j:log4j:jar:1.2.15:compile

[INFO] |  \- org.codehaus.woodstox:wstx-asl:jar:3.2.7:compile
[INFO] |     \- stax:stax-api:jar:1.0.1:compile

Clearly there is an inconsistency with solr/dist/solrj-lib and this list.

• lucene-core dependency should be removed
• AFAIK, geronimo-stax-api and wstx-asl are only needed for Java 1.5. Right? These can be put in a maven profile activated by jdk1.5.
• zookeeper dependency should be removed. Is this used in Solr 4? Even if it is, it strikes me as an optional dependency.
